Find s for the given planes 2x + 2y + sz + 2 = 0 and 3x + y + z – 2 = 0, if they are perpendicular to each other.
Find s for the given planes 2x + 2y + sz + 2 = 0 and 3x + y + z – 2 = 0, if they are perpendicular to each other. Correct Answer – 8
If their normals are perpendicular to each other then a1a2 + b1b2 + c1c2 = 0. 2(3) + 2(1) + s(1) = 0 s(1) = – 8 k = – 8
